IMPROVEMENT-1N WINDOW-SHADE HANG lNG S Specification forming part ofLetters Patent No. January To all whom it may concern:

Be it known that I, JOSEPH HUNKELER, of Lowell, North St. Louis, in thecounty of St. Louis and State of Missouri, have invented a new anduseful Improvement in Window- Shade Hanging specification.

My improvements relate to windowcurtain hangings of the class thatpermits the adj ustment of the curtain to admit light at the top orbottom of the window to any desired extent.

The invention consists in combining with a curtain-roller a second roll,hung in the loops of flat belts that are attached at one end to thewindow-frame, and connect the flanged spools on the ends of the rolls,as hereinafter described.

In the accompanying drawings, Figure l is a front elevation of myimproved hangings as applied to a window. Fig. 2 is a vertical sectionon line :10 {E of Fig. 1. Fig. 3 is a similar view on line y y. Figs. 4and 5 are, respectively, a face view and section of the cord-tightener.

Similar letters of reference indicate correspondin g parts.

The curtain a is attached upon a roller, b, that has flanged spools c ateach end, and the curtain and roller are sustained in the loops of flatbelts d, that are attached by one end to the window-frame at 0, and pass:around s, of which the following is a spools c, and are wound on spoolsc e of the upper roller, f, that is fitted in brackets g at the top ofthe window, so that roller 1) may turn in its supporting-loops to windup or unwind the curtain, or may be lowered by un Winding belts d, andthe roller 1) held at any point in the length of the window.

The roller fis provided with a friction-cord, h, for operating it, whichcord passes over a 216,187, dated June 3,1879; application filed 20,1879.

tightener, B, attached at the lower part of the window-frame.

The cord-tightener I make use of consists of a bent arm-piece, t,carrying a frictionroller, and extending through the vertical slot of acase, 70, in which case it is connected to a spiral spring, a, that isheld to the case by a bent arm-piece, l, extending through the slottedcase, and. clamped by a nut, m. The case It is serrated along the edgesof the slot,

so that the nut may take a good hold.

By this construction the cord his held by spring tension, and may beadjusted to render it more or less tight.

By operating cord h the beltsd are wound on spool e, or unwound, and theroller bthereby positioned at any point in the length of the window, asillustrated in the drawings, and light thereby permitted to enter at theupper part of the window. In thisposition of roller 1) the curtain maybe rolled up or with a tightener, and provided with end-- flangedspools, of a similarly-provided roll, b, suspended in the loops of flatbelts (I, attached at one end to frame, and connecting with spools c c,as shown and described. r
